polkagris
Polkagris (plural: polkagrisar) is a Swedish stick candy that was invented in 1859 by Amalia Eriksson in the town of Gränna, Sweden. It remains a well-known albeit old-fashioned candy in Sweden, often sold at fairs, Christmas markets, and the like. It is still closely associated with Gränna. The traditional polkagris candy stick is white and red, and is peppermint-flavoured.
